What does phase powering mean on mobo

[ICIT2LOL]

Am planning a new build and the Asus P8Z77-V board is cheaper by $40 than the Asus P8Z77-V Pro but has 8 phase power as opposed to the Pro with 12 phase power.

Now I have done a quick Google and there are refs to this but could someone put it in plain / basic wording as there are some refs to CPU power supply, vdroop, and other tech stuff that I don't really understand??

I intend running an i5 3570K and have try at over clocking - if that has any relevance for what my query is about.

The voltage from the power supply has to be reduced to the smaller voltage required by the chip, and delivered at high current. Switching Voltage Regulator Modules are used to do this stepping down of the voltage very efficiently with little power lost to heat. The power the VRM supplies has to have very little ripple and must respond quickly to changes in load. Using multiple VRM modules (phases) increase the response and reduces ripple. The more the better.

8 phases should be plenty except for extreme overclocking.

Thanks Gene for such a plain English explanation - have worked building power supplies for small projects over the years and know what this is about now.

The fellows in the Youtube vid on this board as a lot of the company reps do - take it for granted that everyone knows what they are talking about but am now on track thanks again to your post

I actually just ordered a similar board and was wondering the same thing.

Hum thats a good price UR out here it's $199 and I was going to get the Pro but hey one less USB header and the phase being enough not worth he hassle , just hope I can fit the Arctic Freezer 13 onto it without clouting the RAM sticks and other gear otherwise I'll have to go fluid.
-Really nice piece of gear if you are looking at an air cooler and almost silent.

My i5 2500 on an H67 board idles at 22C now whereas the stock cooler ran 38 - 54C. Am using Arctic Silver on it too. I was going to use that Antec 7 nano diamond stuff but after putting it under another Arctic Freezer 13 I can only get 33C at idle using a Q9650 at 3.0Ghz so am going to stick to the AS thermal.
